Product Description

Applications of OP7 and OP17

Operator and malfunctions of a connected PLC to be visualized. In addition, inputs can be made on the OP which can be written directly to the PLC. Some functions relating to machine diagnostics can also be executed on the Operator Panel.

The Operator Panels feature a number of standard functions. The displays and operation of the devices can be optimized by the configurer to meet the requirements of the process.

The Operator Panels are suitable for fitting into switching cabinets and con trol desks. A printer can be attached to the OP for logging processes during automation operation.

1.1 Configuration

Creating data areas

Before visualizing data from the PLC, i.e. it has to be configured. As far as the PLC is concerned, data areas used by the OP to communicate with the PLC have to be created in the memory

Screens

Event messages

Data supplied by the PLC may be displayed together on a screen and modi fied individually since, for example, more related data are required for describing a machine state than can normally be displayed in the window of a screen. Therefore data on operating temperature, fill level, speed and running time can illus trate the current machine state.

The OP7 and OP17 are Operator Panels with text based displays. Accordin gly

, a screen on the display comprises text items which may include static

text and current state values. Screens may be combined on the OP in a directory

to display

Event messages are information and operating notes on current machine and process states during regular production operations. Event messages may contain process values. Process values are displayed either numerically - for example,

The classification of a message as an alarm message is made at the configu

ration stage.

When a product is made up of various ingredients in certain ratios, this infor mation is stored in a so-called recipe.

Each recipe can be made up of several data records containing dif

ferent va

, transferred to the PLC and read out from

the PLC. In the OP

, the recipes are combined by recipe number and title in a recipe

directory.

Help text consists of configurable additional information and operator in structions relating to event messages, alarm messages and screens. If for ex

Time response of data updating

With

the OP7 and the OP17, updated and newly created data are stored in a

non-volatile flash memory

. This means that current data are immediately

available following an OP re-start. The flash memory cannot be accessed while data are being updated, and the

OP cannot be operated. The update rate is determined by the time response of the delete and write cycles of the flash memory

. For technological reasons,

this rate is slower than the access time for volatile memories. A system message is output to the OP while data updating is in progress.

Message bit procedure

there is a condition present in the current process for a message to be issued – for example, a tag has been reached – a bit is set by the PLC ap plication program in the data area for event and alarm messages. The OP reads the data area after a configured polling time. In this way detected as having ”arrived”. The bit is reset by the PLC when the condition for issuing the message no longer exists. The message is then regarded as having ”departed”.

7.1.2 Alarm messages

Due

Acknowledging an alarm message

to their critical nature, alarm messages have to be acknowledged. This

can be done manually by the operator or automatically by the PLC.

o acknowledge an alarm message manually

The OP displays unacknowledged alarm messages in flashing mode. The LED assigned to the Acknowledge key (icon

ACK

Acknowledgement groups, group acknowledgement

Inhibiting the display of alarm messages

If several alarm messages are waiting to be displayed, after one has been acknowledged the next one is shown, which similarly has to be acknowledged.

If no more alarm messages are waiting to be displayed, the OP reverts to the operating level from which it branched to the message level to display the alarm messages.

During configuration, you can combine several alarm messages to form an

”

acknowledgement group”. In this way you can acknowledge all the other

alarm messages (consequential faults) in that acknowledgment group by ac

knowledging the first alarm message – for example, the cause of the fault – without all of them having to be output to the display on the OP (group ac knowledgement). Y

ou can configure up to four acknowledgment groups.

If alarm messages are not assigned to an acknowledgment group, only the one that happens to be on the display is acknowledged if more are waiting.

There is the possibility of inhibiting the display of frequently occurring alarm messages for the time being until the OP starts up as a result of a cold or warm start. Before you can inhibit the display of an alarm message, you must have logged onto the OP with a password having a password level of at least 8.

Inhibiting system messages

System message buffer

System messages are classified as serious and non-serious system messages. A serious system message is based on an error that can be rectified only by a cold or warm restart of the OP

. All other errors generate a non-serious system message – for example, when printing has been initiated but a printer has not been connected to the OP

If the display of a non-serious system message is not automatically canceled after a short while, you can do so manually by pressing this system key

ESC

Display of a non-serious system message can also be canceled automatically when a configured display time has expired.

A list of possible system messages and their explanations will be found in the appendix B of this manual.

Display of system messages (with the exception of internal errors 7xx) can be inhibited at the configuration stage. System messages whose display has been inhibited continue to be inserted into the system message buf be viewed on the display later

A recipe is identified by a recipe number and a recipe title specified during configuration. A data record is identified by a data record number and a data record name assigned in the OP

The clear and unmistakable identification factor for a data record is the data record number and not the data record name.

This means that, although several data records with the same name may exist, several data records with the same number cannot exist. If no name is assigned to a data record, it is assigned the name ”data record”.

Updating values

If the cursor is located in the first field and if input has not been started and updating is not in progress, you can insert a new tag line in front of the cur

When you have finished editing the operand list, the values on the PLC have to be updated. This is not done immediately after an individual value has been entered. Not until you press the Enter key again after entering the final value is updating of all the new values explicitly initiated. During updating, a flashing asterisk, *, is visible in the top right corner of the display

. If the asterisk does not flash, this means that the OP did not succeed in establishing a logical link to the PLC.

Inputs cannot be made while updating is in progress. Updating can be canceled by pressing

Local means that the assignment applies to one screen entry only for the operator to initiate functions as and when required by the situation.

A password level may be assigned to a function key or a soft key

(red/green).

Convenient operator prompting can be implemented by means of the option of activating the LEDs on function keys (refer to Chapter 13).

A bit can be configured in a tag for every soft key

. This insures that a bit is set in the PLC when a soft key is pressed. In this instance, the OP always transfers the whole tag to the PLC instead of the individual bits and over

writes the information it contains. When the key is released or upon a change of display which modifies soft-

key assignment, the bit is reset.
